High-Intensity Mechanical Pretreatment and High-Compression Screw Pressing for Deresination of Aspen Kraft Pulps, 1994 Pulping Conference Proceedings

S.C.H. Tay, M.D. Ouchi, F.B. Cramer

The wood resin in aspen kraft pulps is predominantly encapsulated in ray parenchyma cells that protect it from removal during normal diffusion washing. Hence, conventional pulp washing operations which use multiple-stage drum washers or diffusion washers cannot effectively remove the resin. The resulting high level of residual resin entering the paper mill with the pulp exacerbates pitch deposition problems at the paper machine and degrades product quality.
